Do
not operate until problem is
solved. Operation while problem is le

Danger
of
overhea
ting
Install in a
well""""'lent
ilated area. Poor ventilation
can disrupt cooling and c
au
se accident, failu
re
or
bodily injury such
as
bu
rn
s since this vacuum
pump is an air-cooled type.
Danger of
unbalanc

Be
su
re to Install on solid and level floor (less Ih

inclination).
Uneven installation can cause failure and
movement of vacuum pump.
If
installat

unstable, fix pump base with
4

holes of pump
leg (ISP-25OC)
or
4-M 1 0 tap section pump base
(ISP-50OC).
Mo
tor
burnout
Belore doing any wiring, check electric source and
vollage.
Single-phase is a multi vollage type of
AC
100V/AC200V. Three-phase is a multi voltage
type
of
AC200V!AC400V. Voltage can be changed
at terminal block. This
!;1um!;1
is wired
to
200V
when delivered to you. Check your electric source,
vo
llage, and wire correctly to terminal block.
Impruper wiring and
Incorrect voltage can cause
motor burnout.
Danger
of
exhaust d
isr
upt
ion
Remove blank flange from Inlet and outlet.
Operation with blank flange being
filled can disrupt
exhaust or cause blank flange to
Ily by exhaust
Impe
tu
s,
resulling in accident,
fa
ilure, or bodily
Injury
from contact with flylng objects.
Danger
of
exh
aust
d
isr
up
tio
n
When
connecting exhaust piping to vacuum pump
and when combining piping with another vacuum
pump. pay
allention to piping size and length so
that it does not cause exhaust resistance. Exhaust
resistance can disrupt air
flow, resulting in fai ture
and over-currenl.
Danger of abnormal sound and fail
ur
e
Open inlet to atmosphere lor about 5 seconds
before restarting vacuum pump.
II not, it can unbalance temperature Inside vacuum
